Title: Petroleum burner
Inventor: ISOBE TAKASHI
IPC: F23D11/44
Filed: 1987-04-09
Abstract: PURPOSE:To prevent sudden generation of red flames by providing a metal net of steel material which has heat resistance and minute corrugated shape at the inner wall of the bottom face of a carburetor cylinder. CONSTITUTION:A throttle device 5 is provided at the upper section of a carburetor cylinder 1. The throttle device 5 serves mainly for promoting the mixing of the vaporized fuel which flows in and the air, and the mixture gas flow which ascends through said throttle device 5 passes through a flow straightening member 7 and flows to the outer circumference from the central opening of a flow dividing plate 8 and burns by a flame hole section 6. At the bottom face of the carburetor cylinder 1 a metal net 10 of steel material is provided. With the above described constitution, even during the control at most suitable vaporization conditions by a temperature sensing element which becomes a heating control device for a heater 4 provided at a section of the carburetor cylinder 1 or during the state of vaporization under high temperature over 280 deg.C, the kerosene particles which hit the face opposite to the nozzle 2 of the carburetor cylinder 1 are always prevented from sudden dispersion by the corrugated surface of the metal net 10 so that no red flame is developed during the combustion at the flame hole section 6 through the throttle section, etc.

Inventor: KONDO IKUO
IPC: B68G7/052
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a cover mounting structure of a vehicle seat which can prevent the application of peeling load to the longitudinal ends of hook-and-loop fasteners. SOLUTION: A predetermined-length unbonded part 15 with respect to the bottom surface of a grooved part 6 is provided at the longitudinal end of one hook-and-loop fastener 9, and therefore even if peeling load F is applied to the longitudinal end of a cover 4, the peeling load F simply pulls both of the fasteners 9, 12 in the peeling direction while the fasteners 9, 12 are held joined together, and does not work to peel the longitudinal ends of the hook-and-loop fasteners 9, 12 from each other. Therefore, the bonding strength of the hook-and- loop fasteners 9, 12 is enhanced to enhance the mounting strength of the cover 4.

Title: Driving force transmission system
Inventor: SAITO HIDEYUKI
IPC: F16D43/284
Filed: 1990-04-02
Abstract: PURPOSE:To obtain a weak transmission force when the differential rotation is low so as to evade a tight corner braking phenomenon, deterioration of fuel consumption and aggravation of driving feeling, while to obtain a strong transmission driving force when the differential rotation is high by forming a recessed portion on each end of a pair of variable blades in the rotating direction contained in a space area. CONSTITUTION:When a relative rotation occurs on two shafts 3, 4, a rotor 21 rotates inside a space area 20 and the high viscosity fluid is forcibly moved by a pair of variable blades 25a, 25b which rotate together with the rotor 21. Next, when the differential rotation is low, the generating pressure for the differential rotation is low and thus the tight corner braking phenomenon and the like can be evaded because of the multiple movements of high viscosity fluid in between the space areas separated from the rotor 21 by the clearance. As the differential rotation gradually increases, the clearance becomes smaller as the variable blades move to an actuating piston 7 and a housing 2 sides, respectively. Due to this reason, the movement of the high viscosity fluid in between the space areas separated by the rotor through the clearance reduces and the generating pressure inside the space area increases.

Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To detect the endpoint of plasma treatment in a stable and highly precise manner, by a method wherein a signal component is extracted in accordance with the progress of plasma treatment, and the end point of plasma treatment is detected, based on the change of the extracted signal component. SOLUTION: A sampling signal 72 is generated in a sampling signal generating circuit 69, based on the high frequency signal sent from a signal generator 37. The phase of the sampling signal 72 is adjusted in the desired amount, in accordance with the waveform of emitted light by a phase shifter 65. More specifically, the phase of the sampling signal 72 is adjusted so that the high peak component, which greatly changes when the end point is detected, is sampled. Subsequently, the sampling signal is sent to a signal treatment circuit 56, the high peak, which changes greatly at the endpoint, is selectively detected and outputted. This output signal is sent to a low-pass filter 57, and a light- emitting signal is obtained. The time when signal intensity is suddenly attenuates is the end point of etching.  The accuracy of detection of the end point for etching a microscopic pattern can be enhanced through this method.

Filed: 1985-04-26
Abstract: PURPOSE:To enable to remove background ions and to detect ions of a very small quantity of sample with a good S/N, by furnishing slits in front of and at the rear of a quadruple pole lens. CONSTITUTION:Although ions to be detected pass through around the center of the ion optical axis, ions other than those are deflected out of the axis by a magnetic field, to enter a quadruple pole lens 4, and some may reach a collector after hitting the gas or hitting and reflecting at an electric field electrode. To remove such ions, a slit is formed to control the ions entering the quadruple poles 4 to limit ions to the ions close to the axis, and another slit is also formed at the outlet side to limit the output ions to the ions close to the axis. The positions of these slits are not at the focusing point of the ion beams, but only the incident ions to the quadruple pole lens at a restricted angle can pass through the two slits. Therefore, ions to cause a scattering or other backgrounds can be removed.

Title: Current mirror circuit
Inventor: OKODA TOSHIYUKI
IPC: H03F3/343
Filed: 1986-04-17
Abstract: PURPOSE:To attain the normal operation of the titled circuit up to a considerably low power voltage without increasing the chip area by forming the 1st and 2nd transistors (TR) constituting the current mirror circuit by TRs whose base is formed by an active base region of a low density. CONSTITUTION:The 1st and 2nd TRs 1, 2 constituting the 1st current mirror circuit 3 are formed by a P<-> type active base region 36 formed on the surface of an island region 35 being a collector, an N<+> type emitter region 37 formed on the surface of the active base region 36 and a P type base contact region 38 being partly overlapped to the active base region 36, Since the base of the TRs is formed by the low density active base region 36, the current rising characteristic of the emitter-base junction is more excellent than a conventional TR and the carrier transportation efficiency at the base is high, then the probability of minority carriers injected from the emitter reaching the collector is high even when the collector potential is insufficient. Thus, the circuit is operated normally even with a considerably lowered power voltage.

Title: Cmos semiconductor device
Inventor: SHINOHARA TOSHIAKI
IPC: H01L27/08
Filed: 1987-04-13
Abstract: PURPOSE:To improve breakdown strength against latch-up, by embedding a recombination layer for recombining minority carriers in an either region of a semiconductor substrate or a well, in such a way that an interval is provided from the junction between the semiconductor substrate and the well so as to avoid contact with a depletion layer, which is formed at said junction. CONSTITUTION:A recombination layer 105 for recombining minority carriers is embedded in a part at the junction plane between the region of a semiconductor substrate 10, i.e., an element region substrate 102, and a lower substrate 101. The region of the substrate 10 is separated from the p-n junction, which is formed at the interface part between the n-type element region substrate 102 and a p-type well, by a thickness of a depletion layer, which is formed at the p-n junction, or more. Since the recombination layer 105 is formed in the region directly beneath the p-type well 2 in this way, holes, which are injected into the element region substrate 102 from a p<+> drain region 9 and a p<+> source region 8, are trapped in the recombination region layer 105 and recombined with electrons. Thus the holes disappear. The holes reaching the p-type well 2 are suppressed to a very small amount. Thus the breakdown strength against latch-up is improved to a large extent.
